Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Approximately 3% hysteresis is provided to ensure stable operation

Note 4: The oscillator frequency is not tested directly but is inferred from

turn-on time.

Note 5: SMBus timing specifications are guaranteed but not tested.

Note 6: ON is enabled upon receiving the Stop condition from the SMBus

master.

Note 7: OFF is enabled upon receiving the Stop condition from the SMBus

master.
